The document provides information on wind energy, including: 1) It explains how wind is formed from differences in air temperatures and how this kinetic energy can be captured by wind turbines to generate electricity. 2) It discusses the history of wind power usage dating back thousands of years and the development of modern large-scale wind turbines in the late 19th century. 3) It notes the potential for wind power in the US, especially in the Dakotas and Texas, to generate enough electricity to power the entire country.
